Highlighting an important but unexplored area of evolution, scientists at The Scripps Research Institute (TSRI) have found evidence that, over hundreds of millions of years, an essential protein has evolved chiefly by changing how it moves, rather than by changing its basic molecular structure. The work has implications not only for the understanding of protein evolution, but also for the design of antibiotics and other drugs that target the protein in question.

An international consortium of scientists has identified an additional 48 genetic variants influencing the risk of developing multiple sclerosis, MS. This work, which is presented in the journal Nature Genetics, nearly doubles the number of known genetic risk factors associated with MS - and thereby provides additional key insights into the biology of this debilitating neurological condition, globally affecting millions of people.

Researchers have compiled the largest and most rigorously validated list to date of the genetic sites in fruit flies where RNA transcribed from DNA is then edited by an enzyme to affect a wide variety of fundamental biological functions. The list yielded several biological insights and can aid further research on RNA transcription because flies are a common model in that work.

A problem developing more efficient organic LED light bulbs and displays is that much of the light is trapped within the light-emitting diode, or LED. Physicists believe they have solved the problem by creating a new organic molecule that is shaped like rotelle – wagon-wheel pasta – rather than spaghetti.

Scanning the DNA of nearly 5,000 tumor samples, a team led of scientists has identified 140 regions of scrambled genetic code believed to contain many undiscovered cancer genes. Mapping of the abnormal regions gives cancer scientists a starting point from which to search for as-yet undiscovered oncogenes and broken tumor-suppressor genes.

A tiny chip used in smart phones to adjust the orientation of the screen could serve to create a real-time urban seismic network, easily increasing the amount of strong motion data collected during a large earthquake.

Israel's southern Red Sea resort of Eilat, one of whose prime attractions is its colorful and multi-shaped underwater coral reefs, may have a clear advantage in the future over rival coral-viewing sites around the world, scientists have found.

Clinical trial design for new cancer therapies has historically been focused on the tissue of origin of a tumor, but a paper published in Nature Genetics supports a new approach: one based on the genomic signature of a tumor rather than the tissue of origin in the body.

Infants show strong universals as they acquire their native language, but a recent study with infants acquiring Korean also reveals that there are striking language differences. A new study provides the first ever evidence comparing how infants (monolingual, from Korea) acquiring Korean learn new nouns and verbs.

In a first-of-its-kind study to evaluate the impact of a medical specialty on patient outcomes, researchers found that hospitalized patients with severe infections such as meningitis and Clostridium difficile are significantly less likely to die if they receive care from an infectious diseases specialist. The study analyzed nearly 130,000 Medicare patient cases.

A diagnosis of multiple sclerosis (MS) is a hard lot. Patients typically get the diagnosis around age 30 after experiencing a series of neurological problems such as blurry vision, wobbly gait or a numb foot. From there, this neurodegenerative disease follows an unforgiving course.

Americans in the highest socio-economic groups have a 13 percent greater chance of surviving a kind of stroke known as a subarachnoid hemorrhage than those in the lowest socio-economic groups, a new study has found.

The blockage of the immune response with anti-inflammatory drugs reduced the progression of squamous cell carcinomas (SCCs). This strategy could be effective in treating up to 75 percent of human patients with SCC. The study reinforces the important role of inflammation in the development of cancers and opens up a new path for the treatment of the disease.
